# Helicone Is in Maintenance Mode: The Migration Map for Founders Still on It

> Mintlify bought Helicone on March 3, and the open-source LLM observability tool now ships security patches and new-model support but no new features and no roadmap. Here's whether you have to move, and exactly where to go depending on what you used it for.

## Key takeaways

- Helicone still works — the decision isn't 'is it broken,' it's 'do I want my observability on a tool with no roadmap.'
- On March 3, 2026, Mintlify acquired Helicone and its founders; the product moved to maintenance mode — security patches, bug fixes, and new-model support continue, but new integrations, new analytics, and forward roadmap have stopped. The Apache-2.0 repo is still MIT-of-the-gateway-world open and self-hostable, so nothing turns off tomorrow.
- Whether you must move depends on WHAT Helicone was for you, because it was two products in one: an observability dashboard (traces, cost, token counts) AND an AI gateway (caching, rate-limiting, routing, failover). Split the decision along that line.
- If you used it as a cost/trace dashboard: move to Langfuse (open-source, OTel-native, now ClickHouse-backed) or Arize Phoenix (open-source, self-host) — both are actively developed and framework-agnostic.
- If you used the gateway: move to LiteLLM, Portkey, or Bifrost, which are still shipping gateway features.
- The durable lesson: Helicone's one-line proxy swap was its best feature and its trap — it put a vendor on your critical request path. Re-instrument on OpenTelemetry instead, and your next observability vendor is a config change, not a migration.

## At a glance

| What you used Helicone for | The risk now | Where to go |
| --- | --- | --- |
| Cost + token dashboard | Falls behind new providers/models over time | Langfuse or Arize Phoenix — open-source, OTel-native, actively developed |
| Request tracing + debugging | No new analytics or trace features shipping | Langfuse (full-text trace search, evals) or Phoenix |
| Gateway: caching / rate-limit / routing / failover | No roadmap for gateway features | LiteLLM, Portkey, or Bifrost — dedicated, still shipping |
| The one-line proxy swap | Puts a no-roadmap vendor on your critical path | Re-instrument on OpenTelemetry — make the backend a config change |
| Self-hosted OSS deploy | Keeps working; slowly stagnates | Stay if it's low-risk; otherwise migrate on your own schedule |

## By the numbers

- **Mar 3, 2026** — Mintlify announced its acquisition of Helicone; the product moved to maintenance mode
- **14.2T** — tokens Helicone had processed at acquisition — this is real infrastructure, not a toy, which is why an orderly exit matters
- **~16,000** — organizations on Helicone when it was acquired
- **Apache-2.0** — Helicone's license — the self-hosted build keeps working, so you migrate on your schedule, not a vendor's
- **1** — environment variable — what switching observability backends should cost you if you instrument on OpenTelemetry instead of a proxy

**The short version:** on **March 3, 2026**, [Mintlify acquired Helicone](https://www.mintlify.com/blog/mintlify-acquires-helicone) and its founders, and the open-source [LLM observability](/topics/agent-evals) tool moved to **maintenance mode** — security patches, bug fixes, and new-model support keep shipping, but **new features, new integrations, and the roadmap have stopped**. [Helicone](/stack/helicone) is Apache-2.0 and self-hostable, so nothing turns off on a deadline. The decision isn't *"is it broken."* It's *"do I want my cost tracking and agent debugging on a tool that will never ship another feature."* For most founders the answer is *migrate — calmly, on your own schedule.* Here's the map.
What "maintenance mode" means, exactly
It means the lights stay on and the roadmap goes dark. Per [Helicone's own announcement](https://www.helicone.ai/blog/joining-mintlify), the team — Justin Torre and Cole Gottdank — joined Mintlify, and the product now gets security fixes, bug fixes, and support for newly released models, but **no new analytics, no new integrations, no net-new development**. At acquisition Helicone had processed **14.2 trillion tokens** for roughly **16,000 organizations** — this is real infrastructure, which is exactly why you want an orderly exit rather than a scramble.
So: your dashboards keep working with today's providers. What you lose is the thing a live competitor gives you for free — the drip of new features every month, and confidence that next year's models and frameworks will be first-class.
The trick to deciding: Helicone was two products
Most write-ups miss this. Helicone bundled **two separable things** behind one base-URL swap:
- **An observability backend** — traces, token counts, cost per request, request logs, evals.
- **An AI gateway** — caching, rate-limiting, provider routing, failover.

Your migration depends on which one you actually leaned on. Split the decision along that seam and it gets simple.
If you used it as a cost + trace dashboard
Move to an **actively developed, open-source, OpenTelemetry-native** platform. In practice that's [Langfuse](/posts/tool-highlight-langfuse-llm-observability-and-evals.html) or [Arize Phoenix](/posts/tool-highlight-arize-phoenix-self-host-agent-tracing-evals.html).
[Langfuse](/stack/langfuse) is the safe default: MIT-licensed core, free to self-host, tracing + cost tracking + evals + prompt management, and — the part that matters here — [it was acquired by ClickHouse in January](/posts/clickhouse-langfuse-acquisition-llm-observability.html), so it's the *opposite* trajectory to Helicone: better-funded and shipping harder. Phoenix is the other solid open-source pick if you want trace-and-eval tooling you run yourself. Both are framework-agnostic, so you're not trading one lock-in for another. If you're weighing them, we've already put them [head to head for a solo founder](/posts/langfuse-vs-arize-phoenix-vs-braintrust-llm-observability-solo-founder.html) and [as self-host options](/posts/langfuse-vs-opik-vs-phoenix-open-source-self-host-observability.html).
> The bundling that made Helicone a one-line install is exactly what makes leaving it a two-tool job. That's not a tax — it's the fix.

If you relied on the gateway
If what you loved was the caching, the rate limits, the routing across providers, and the failover — that's the gateway, and there are dedicated ones still shipping: **[LiteLLM](/stack/litellm)**, **[Portkey](/stack/portkey)**, and **Bifrost**. We [compared the three](/posts/bifrost-vs-litellm-vs-portkey-llm-gateway-2026.html) recently; any of them replaces the gateway half of Helicone without dragging your observability along for the ride.
Yes, you now run a gateway *and* an observability backend where you had one box. Keep them separate anyway — it's why your *next* migration will be a config change instead of a project.
The real lesson: the proxy was the trap
Helicone's best feature was that you swapped `api.openai.com` for `oai.helicone.ai` and were done — no SDK, no code change. That convenience is also what welded a third party onto your **critical request path**. When that party stops shipping, you're stuck moving the thing every request flows through.
The durable move is to stop instrumenting on a proxy and start [emitting OpenTelemetry GenAI traces from your app](/posts/instrument-agent-opentelemetry-genai-traces-send-anywhere.html). Do that and the observability backend becomes a *destination* — any tool that speaks OTLP (Langfuse, Phoenix, and most of the field) is one `OTEL_EXPORTER_OTLP_ENDPOINT` away. [The trace is the new log](/posts/the-trace-is-the-new-log.html); own the trace, rent the dashboard. While you're re-plumbing, it's also the right moment to [redact PII before traces leave your perimeter](/posts/redact-pii-secrets-agent-traces-before-observability-vendor.html) and to [tail-sample so the observability bill doesn't scale with traffic](/posts/how-to-tail-sample-agent-traces-cut-observability-bill.html).
The one-line decision
- **On self-hosted Helicone, low stakes?** Stay for now — it keeps working. Just don't build anything new on it.
- **Using it for cost + traces?** Migrate to **Langfuse** (or Phoenix). Both are open, OTel-native, and shipping.
- **Using the gateway?** Move that half to **LiteLLM / Portkey / Bifrost**, separately.
- **Doing either?** Re-instrument on **OpenTelemetry** first, so the vendor after this one is never a migration again.

Helicone isn't a cautionary tale — it's a genuinely good tool that got acquired, which happens. The cautionary tale is putting a single vendor on the path every one of your requests takes. Fix that once, and the next acquisition is somebody else's fire drill.

## FAQ

### Do I have to migrate off Helicone right now?

No. Helicone is open-source under Apache 2.0 and self-hostable, and Mintlify says security patches, bug fixes, and new-model support continue. Nothing shuts off on a deadline. The real question is forward risk: with no new features, no new integrations, and no roadmap, a tool you depend on for cost control and debugging slowly falls behind the models and frameworks you actually run. Treat this as a plan-your-exit event, not an evacuate-tonight one — migrate on your schedule, before a gap in coverage forces it.

### What does 'maintenance mode' actually mean here?

Per Helicone's and Mintlify's announcements, it means the lights stay on but the roadmap stops: security fixes, bug fixes, and support for newly released models keep shipping, while new integrations, new analytics features, and net-new development do not. The founders, Justin Torre and Cole Gottdank, joined Mintlify. So expect the tool to keep working with today's providers, and expect it to stop gaining the features a live competitor ships every month.

### Where should I go if I used Helicone mainly for cost and token tracking?

To an actively developed, open-source, OpenTelemetry-native platform — practically, Langfuse or Arize Phoenix. Langfuse gives you tracing, cost tracking, evals, and prompt management, is MIT-licensed at the core, self-hostable for free, and is now backed by ClickHouse. Phoenix is open-source and self-hostable with strong trace/eval tooling. Both are framework-agnostic, so you are not trading one lock-in for another.

### Where should I go if I relied on Helicone's gateway features (caching, routing, failover)?

To a dedicated LLM gateway that is still shipping: LiteLLM, Portkey, or Bifrost. Helicone bundled a gateway into an observability proxy, which is why moving off it can mean picking two tools where you had one. That is fine — a gateway and an observability backend are cleanly separable, and keeping them separate is why the next migration will be easier.

### How do I avoid this exact situation with the next vendor?

Instrument on OpenTelemetry, not on a proprietary proxy. Helicone's killer feature was swapping one base URL — no code change — but that convenience is what welds a vendor onto your live request path. If instead your app emits OTel GenAI traces, any backend that speaks OTLP (Langfuse, Phoenix, and most others) becomes a destination you point at with an environment variable. The vendor becomes swappable; the instrumentation stays put.
